If you have started to notice small, green bugs on your fiddle leaf fig, you might have an aphid problem. Aphids will tend to form little colonies on your plants foliage and new stems, so be sure to check these areas in particular.
Aphids reproduce quicker than rabbits, thus can become a big problem if not dealt with quickly. Aphids feed on plant sap. Infestations of aphids will remove excessive amounts of sap from your fiddle leaf figs foliage. When this occurs you will notice that the aphid infested leaves will wilt and turn yellow.
Aphids are a common pest and there are a varieties of ways to deal with them once identified. Treatments include store bought pesticides/ insecticides as well as essential oils and other home made remedies.

Scale insects are easily identifiable on your fiddle leaf fig. Scale bugs are small, flat, oval shaped bugs with brown shells (think of little brown lady bugs). You will find scale insects hidden underneath the foliage on your fiddle leaf fig as well as on the stem where leaves connect.
Similar to aphids scale insects also feed on your house plants sap. This removal of sap can lead to the wilting of leaves and or cause them to yellow. Foliage on your fiddle leaf fig will sadly not recover from this damage so if you want to keep your plant happy and healthy it is important to deal with scale insects as soon as possible.
Depending on the degree of infestation of scale insects that you have, scale insect treatment varies. If there are small amounts of bugs, you can remove them from your fiddle leaf fig via hand or cloth. Essential oils, such as neem oil, and high content alcohol solutions will kill scale when applied with a cotton bud. Pesticides and beneficial insects (lacewing and lady bugs will eat scale) are great control methods for larger infestations.
There a few species of mite that can harm your fiddle leaf fig, however we will only be covering the most common of these, the spider mite.

Essential oils are a great natural way to treat mites, you can see more information on treating mites with essential oils here. Preventing mites and the damage they cause is simple, keep your fiddle leaf fig in top condition. Alternatively predator bugs are also a great preventative.
As the name suggests, Whitefly are small, flying, white colored insects. Similar in shape to moths these little little guys (and girls) are typically found on the top of plants or near the end of stems. Whiteflies are a common pest encountered by house plant keepers and are particularly prevalent in greenhouses.
Feeding on your fiddle leaf figs sap, white fly can cause foliage to yellow and wilt, this can eventuate to stunting your plants growth. Whitefly produce ‘honeydew’ which is a sticky substance which can cause your fiddle leaf fig foliage to become covered in a black mold. White fly are also notorious for transmitting harmful house plant viruses.
It is important for your fiddle leaf figs health to treat white fly in the early stages of infestation. Methods for treating whitefly include;
- Beneficial bug introduction. Predatory insects such as lady bugs feed on whitefly eggs. This method is effective when infestation levels are low.
- Essential oils such as neem oil, mixed with water and sprayed onto your fiddle leaf fig is effective against whitefly regardless of life cycle. Ensure to completely wet all foliage.
- Bug sticky traps, these are especially effective if your fiddle leaf fig is in a controlled environment such as a greenhouse. This technique is not effective at removing eggs from plant so ensure to use this in conjunction.
Mealy bug are similar in size to the previously mentioned scale insects. However; unlike scale insects mealy bugs have a white cotton like appearance. Mealy bugs typically will remain well hidden on your fiddle leaf fig. They gravitate towards the little nooks of the plant including the underside of leaf joints and foliage.
Mealy bugs can breed fast! Females are able to lay up to 100 eggs per sac which can lead to out of control, exponential infestations if not dealt with immediately. Similar to other pests on the list mealy bugs can cause leaves to yellow or die. Stunted growth of your fiddle leaf fig is also common of mealy bug infestation.
Alcohol solutions are effective against mealy bugs with solutions of 60-70% diluted with water effective when applied with a cotton bud directly to mealy bugs. Pesticides and oils are also available to rid mealy bugs. Predatory bugs are also a great control option as well as preventative.
